+# Two bugs while updating a short Subject: header immediately before
+# a still virgin "append header" pointer record.
+#
+# Symptom:
+#
+#    warning: <filename>: malformed pointer record value: <garbage>
+#
+# Cause:
+#
+#    Failure to recognize the "append header" record while updating
+#    a short message header
+#
+# Analysis:
+#
+# This happened while updating a header record that was followed by
+# the current "append header" record. The pointer could be the initial
+# "append header" record between message header and body, or it could
+# be a later version of that pointer somewhere in the heap.
+#
+# - Postfix considered the pointer record as any pointer record after
+# a header record. Thus, it decided that some portion of the pointer
+# record could be overwritten with the location of the new Subject:
+# header on the heap. Later "append header" operations would then
+# update old "append header" record and thus clobber part of the
+# pointer to the new Subject: header value.  
+#
+# - While saving the "append header" pointer record value on the
+# heap, Postfix did not replace the still virgin "0" append header"
+# pointer record value by the actual location of the message body
+# content.
